Has any one run hose for a do-it yourself ballast system on a Malibu 99 Sunsetter LXI (or comparable). Iím curious about any gotchas you may have encountered or ingenious ideas of where you ran yours for your system before I tackle mine.

See Tanks&More on E-Bay. They have all the hose and fittings you need at great prices. The white spiral hose works great for ballast systems. I even replaced my hard PVC with this stuff. They have it in almost any size you need.

I mounted my pump to the ski pylon under the floor. It's mounted up off the floor to keep it dry. I drilled a 1 inch hole from the bilge area into the ski locker. You'll see that the battery cables go through that area too. From there, I 'T'ed off and drilled a hole behind the battery in the storage compartment behind the observer's seat to get a hose into the bow cusion area.

I also ran a hose aft along the steering cable and up behind the back seat where I bring it out the side of the back seat and fill a bag between the engine box and the back seat.

I used a Jabsco Ballast Puppy reversable pump and a thru hull fitting.

Good stuff. I also am filling a sac between the engine compartment and seat. So Iíll follow the path you described. I have a question though about the route through the ski locker. I looked at where they ran the battery cables also, but since I am filling a 375lb sac in the ski locker I thought with the hoses running through there, there might be some restrictions when the sac fills up. My sac takes up the whole locker when Iíve filled it manually. Have you had any issues?
